Description

スパッタ除去具Spatter removal tool
　本発明は、溶接トーチのノズルの内周面及びチップの外周面に付着したスパッタを除去するスパッタ除去具に関するものである。 The present invention relates to a sputter remover that removes spatter adhering to the inner peripheral surface of a nozzle of a welding torch and the outer peripheral surface of a chip.
　通常、溶接作業では、ノズルの内周面及びチップの外周面にスパッタが付着して、シールドガスの流れに乱れが発生し、溶接不良を引き起こす原因となっていた。 Usually, in the welding operation, spatter adheres to the inner peripheral surface of the nozzle and the outer peripheral surface of the tip, and the flow of shield gas is disturbed, which causes welding failure.
　これに対し、特許文献１に記載のスパッタ除去具では、チップ外径より若干大径に形成されたスパッタ除去パイプと、ノズルの外径より若干大径かつスパッタ除去パイプより長く形成されたノズル誘導・保持パイプと、孔が設けられた基板と、を有し、孔を中心として基板同心円上に、スパッタ除去パイプとノズル誘導・保持パイプとを固定していた。 On the other hand, in the sputter removal tool described in Patent Document 1, a sputter removal pipe formed slightly larger than the outer diameter of the chip and a nozzle guide formed slightly larger than the outer diameter of the nozzle and longer than the sputter removal pipe. A holding pipe and a substrate provided with holes are provided, and the sputter removal pipe and the nozzle guide / holding pipe are fixed on the substrate concentric circle with the hole as the center.
　ノズルにスパッタが付着したら、スパッタ除去パイプとノズル誘導・保持パイプとの間の隙間にノズルを挿入し、ノズル外周面とノズル誘導・保持パイプの内周面との間の隙間を利用してノズルを振りながら押し込んでスパッタを除去していた。 If spatter adheres to the nozzle, insert the nozzle into the gap between the sputter removal pipe and the nozzle guide / holding pipe, and use the gap between the nozzle outer peripheral surface and the inner peripheral surface of the nozzle guide / hold pipe to use the nozzle. The spatter was removed by pushing in while shaking.

　しかし、上記スパッタ除去具では、スパッタ除去パイプの軸方向に沿って、ノズルを押し込み、スパッタ除去パイプの先端のエッジでスパッタを除去する構成とされ、ノズルの内径は、スパッタ除去パイプの外径より若干小さい径とされて、スパッタ除去パイプの先端のエッジとノズル内周面とは接触部分が少ないので、スパッタ除去パイプの軸方向に沿って及び軸方向に対して斜めに何度もトーチを出し入れし、かつ、回転させる必要があり、煩雑な動作をしなければならず、ノズル内周面に付着したスパッタを効率よく除去できないという問題があった。 However, the sputter remover is configured to push the nozzle along the axial direction of the spatter removal pipe and remove spatter at the edge of the tip of the spatter removal pipe. The inner diameter of the nozzle is larger than the outer diameter of the spatter removal pipe. It has a slightly smaller diameter, and since there is little contact between the tip edge of the spatter removal pipe and the inner peripheral surface of the nozzle, the torch is taken in and out many times along the axial direction of the spatter removal pipe and obliquely with respect to the axial direction. In addition, there is a problem in that it is necessary to rotate, a complicated operation must be performed, and spatter adhering to the inner peripheral surface of the nozzle cannot be efficiently removed.
　本発明は、上記の課題を解決するものであり、容易にスパッタを除去することができるスパッタ除去具を提供することを目的とする。 This invention solves said subject and aims at providing the spatter removal tool which can remove spatter easily.

　ノズルＮが挿入された状態において、除去片４１及び除去片４２は、短手方向の端縁部４１ｂ、４２ｂが中心線Ｃ（ノズルＮの軸線）に沿って線状に配置され、前後方向（ノズルＮの挿入方向）からみて中心線Ｃ（ノズルガイド部２２の軸線）の周り、かつ、ノズルＮの挿入方向に沿って、配置されている。 In the state where the nozzle N is inserted, the removal piece 41 and the removal piece 42 are arranged such that the edge portions 41b and 42b in the short direction are linearly arranged along the center line C (axis of the nozzle N), and the front-rear direction ( The nozzle N is disposed around the center line C (the axis of the nozzle guide portion 22) as viewed from the insertion direction of the nozzle N and along the insertion direction of the nozzle N.

Edge portions 41c and 42c of the nozzle N are formed so as to be in line contact with the inner peripheral surface N1 of the nozzle N.
　スパッタ除去具１０の動作について説明する。図１に示すように、スライド部２５を、スライド孔３０ｊの前端部に取り付けボルト３０ｋが当たる位置まで本体部２０から引き出し、溶接トーチＺのノズルＮ及びチップＫと干渉しない位置に退避した退避位置に移動させる。 The operation of the spatter remover 10 will be described. As shown in FIG. 1, the slide position 25 is pulled out from the main body portion 20 to a position where the mounting bolt 30k hits the front end of the slide hole 30j, and retracted to a position where it does not interfere with the nozzle N and the tip K of the welding torch Z. Move to.
　ノズルガイド部２２のガイド面２２ｅに溶接トーチＺのノズルＮ及びチップＫを、ノズルＮの先端面Ｎ３が位置決め面２２ｈに突き当たるまで挿入する。これにより、ノズルＮの先端面Ｎ３が受け止められ、ノズルＮ及びチップＫの挿入範囲が決められる。 The nozzle N and the tip K of the welding torch Z are inserted into the guide surface 22e of the nozzle guide portion 22 until the tip surface N3 of the nozzle N hits the positioning surface 22h. Thereby, the front end surface N3 of the nozzle N is received, and the insertion range of the nozzle N and the tip K is determined.
　このとき、連結部４３は位置決め面２２ｈより前側に突出しているが、ノズルＮの中心線Ｃに直交する方向への移動は、ガイド面２２ｅによりノズルＮの外周面Ｎ２が規制されるとともに、チップＫは先端側か細いテーパ状に形成されているので、チップＫはサイズ的な余裕をもってガイド孔４３ａに誘導され、チップＫをキズつけることはない。 At this time, the connecting portion 43 protrudes forward from the positioning surface 22h, but the movement of the nozzle N in the direction orthogonal to the center line C restricts the outer peripheral surface N2 of the nozzle N by the guide surface 22e, and the tip. Since K is formed on the tip side or in a thin taper shape, the chip K is guided to the guide hole 43a with a margin in size, and the chip K is not damaged.
　そして、スライド部２５の押圧操作部３０ｂを手で持ち前側に押し込んで、ノズルＮの内周面Ｎ１とチップＫの外周面Ｋ１との間の隙間部分へ除去部４０を進入させる。押圧操作部３０ｂの前端面と、カラー部２１の後端面とが、突き当たるまで押し込むと、図２、７に示すように、除去部４０の進入が完了した進入完了位置に移動することになる。 Then, the pressing operation unit 30b of the slide unit 25 is held by hand and pushed forward, and the removal unit 40 is caused to enter the gap portion between the inner peripheral surface N1 of the nozzle N and the outer peripheral surface K1 of the tip K. When the front end surface of the pressing operation portion 30b and the rear end surface of the collar portion 21 are pushed in until they come into contact with each other, as shown in FIGS. 2 and 7, the removal portion 40 moves to the entry completion position.
　このとき、ノズルＮの中心線Ｃに直交する方向への移動は、ガイド面２２ｅによりノズルＮの外周面Ｎ２が規制されるとともに、ガイド孔４３ａによりチップＫをガイドすることで、ノズルＮ及びチップＫの芯合わせをしやすくなる。 At this time, the movement of the nozzle N in the direction orthogonal to the center line C is such that the outer peripheral surface N2 of the nozzle N is regulated by the guide surface 22e and the tip K is guided by the guide hole 43a, whereby the nozzle N and the tip. It makes it easy to align K.
　スパッタ除去具１０を、ノズルＮの中心線Ｃ（ノズルＮの軸線）に対して回転させながら引き抜く、このとき図８（ａ）、（ｂ）に示すように、ノズルＮが外れてしまわないように右回りに回すのが望ましい。 The sputter remover 10 is pulled out while rotating with respect to the center line C of the nozzle N (the axis line of the nozzle N). At this time, as shown in FIGS. 8A and 8B, the nozzle N will not come off. It is desirable to turn it clockwise.
　除去片４１及び除去片４２は、ノズルＮがノズルガイド部２２に挿入されたときに、前後方向からみて、ノズルＮの内周面Ｎ１の二点を結ぶ線上に位置して、かつ、互いに平行となるように配置されているので、除去片４１、４２の回転方向前側の短手方向の端縁部４１ｃ、４２ｃがノズルＮの内周面Ｎ１に線接触可能となり、ノズルＮの内周面Ｎ１に付着したスパッタを容易に除去になる。 The removal piece 41 and the removal piece 42 are located on a line connecting two points of the inner peripheral surface N1 of the nozzle N when viewed from the front-rear direction when the nozzle N is inserted into the nozzle guide portion 22, and are parallel to each other. Therefore, the edge portions 41c and 42c in the short direction on the front side in the rotational direction of the removal pieces 41 and 42 can be in line contact with the inner peripheral surface N1 of the nozzle N, and the inner peripheral surface of the nozzle N Spatter adhering to N1 can be easily removed.
　また、貫通孔２１ｇ、スライド孔３０ｊ、貫通孔２１ｈの順に取り付けボルト３０ｋを挿通して、本体部２０とスライド部２５とが締結され、スライド部２５と本体部２０を一体で回転させることになるので、ノズルＮに対して除去片４１、４２を回転させながら引き離す方向に引っ張る作業を容易にするとともに、スライド部２５が本体部２０から抜けてしまうのを防止する。 Further, the mounting bolt 30k is inserted in the order of the through hole 21g, the slide hole 30j, and the through hole 21h, the main body portion 20 and the slide portion 25 are fastened, and the slide portion 25 and the main body portion 20 are rotated together. Therefore, the operation of pulling the removal pieces 41 and 42 with respect to the nozzle N while pulling them apart is facilitated, and the slide portion 25 is prevented from coming off from the main body portion 20.
　ノズルガイド部２２から、溶接トーチＺのノズルＮ及びチップＫを引っ張りだして、スパッタ除去作業が終了したら、図２、７に示す進入完了位置から、図１に示す退避位置に移動させ、次の使用まで待機状態とする。 When the spatter removal operation is completed by pulling out the nozzle N and the tip K of the welding torch Z from the nozzle guide part 22, the nozzle is moved from the entry completion position shown in FIGS. 2 and 7 to the retracted position shown in FIG. It will be in a standby state until use.
　本発明に係るスパッタ除去具１０は、溶接トーチＺのノズルＮ及びチップＫを挿入可能な円筒状に形成され、内周面がノズルＮの外周面Ｎ２をガイド可能に形成されたガイド面２２ｅと、ノズルＮの先端面Ｎ３を受け止めノズルＮ及びチップＫの挿入範囲を決める位置決め面２２ｈと、を有するノズルガイド部２２と、ノズルＮの内周面Ｎ１とチップＫの外周面Ｋ１との間の隙間部分に、ノズルＮの軸線方向に沿って進入してノズルＮに付着したスパッタを除去する除去部４０と、を備えるスパッタ除去具であって、除去部４０は、長尺平板状に形成された除去片４１、４２を備えて構成され、除去片４１、４２は、ノズルＮの挿入方向からみてノズルガイド部２２の中心線Ｃの周り、かつ、ノズルＮの挿入方向に沿って、配置され、位置決め面２２ｈでノズルＮの先端面Ｎ３を受け止めた後、除去片４１、４２の回転方向前側の短手方向の端縁部４１ｃ、４２ｃがノズルＮの中心線Ｃに沿って線状に配置され、かつ、ノズルＮに対して除去片４１、４２を回転させたときに、ノズルＮの内周面Ｎ１に接触可能として、ノズルＮの内周面N 1に付着したスパッタを除去可能とされている。 The sputter remover 10 according to the present invention is formed in a cylindrical shape into which the nozzle N and the tip K of the welding torch Z can be inserted, and an inner circumferential surface is formed so as to be able to guide the outer circumferential surface N2 of the nozzle N. A nozzle guide portion 22 having a positioning surface 22h for receiving the tip surface N3 of the nozzle N and determining the insertion range of the nozzle N and the tip K, and between the inner peripheral surface N1 of the nozzle N and the outer peripheral surface K1 of the tip K. A removal unit 40 that enters the gap portion along the axial direction of the nozzle N and removes spatter adhering to the nozzle N. The removal unit 40 is formed in a long flat plate shape. The removal pieces 41 and 42 are arranged around the center line C of the nozzle guide portion 22 and along the insertion direction of the nozzle N as viewed from the insertion direction of the nozzle N. ,position After receiving the front end surface N3 of the nozzle N with the female surface 22h, the edge portions 41c and 42c in the short direction on the front side in the rotation direction of the removal pieces 41 and 42 are linearly arranged along the center line C of the nozzle N. In addition, when the removal pieces 41 and 42 are rotated with respect to the nozzle N, it is possible to contact the inner peripheral surface N1 of the nozzle N, and it is possible to remove the spatter adhering to the inner peripheral surface N 1 of the nozzle N. Yes.
　これによれば、位置決め面２２ｈでノズルＮの先端面Ｎ３を受け止めるまでガイド面２２ｅに溶接トーチＺのノズルＮ及びチップＫを挿入して、その後、ノズルＮに対して除去片４１、４２を回転させながら引き離す方向に引っ張るという簡単な動作で、除去片４１、４２の回転方向前側の短手方向の端縁部４１ｃ、４２ｃにより、ノズルＮの内周面Ｎ１に付着したスパッタを除去する。 According to this, the nozzle N and the tip K of the welding torch Z are inserted into the guide surface 22e until the tip surface N3 of the nozzle N is received by the positioning surface 22h, and then the removal pieces 41 and 42 are rotated with respect to the nozzle N. The spatter adhering to the inner peripheral surface N1 of the nozzle N is removed by the short edge portions 41c and 42c on the front side in the rotational direction of the removal pieces 41 and 42 by a simple operation of pulling in the direction of pulling away.
　よって、ノズルガイド部２２の中心線Ｃに沿って及び軸方向に対して斜めに何度も溶接トーチＺを出し入れし、かつ、回転させる必要がなくなり、容易にスパッタを剥離、除去することができる。 Therefore, it is not necessary to insert and remove the welding torch Z many times along the center line C of the nozzle guide portion 22 and obliquely with respect to the axial direction, and it is not necessary to rotate, and the spatter can be easily peeled off and removed. .
　また、位置決め面２２ｈにより、ノズルＮ及びチップＫの挿入範囲が決められるので、除去片４１、４２が進入し過ぎて、溶接トーチＺのノズルＮ及びチップＫ以外の部分を傷つけたり、除去片４１、４２の進入が足りなくて、スパッタの除去が足りなくなったりして、溶接不良を引き起こすことを防止することができる。 In addition, since the insertion range of the nozzle N and the tip K is determined by the positioning surface 22h, the removal pieces 41 and 42 enter too much, and the portions other than the nozzle N and the tip K of the welding torch Z are damaged, or the removal piece 41 , 42 can be prevented from becoming poor due to insufficient entry of spatter and insufficient removal of spatter.
　また、筒状に形成され一端側にノズルガイド部２２が配設される本体部２０と、一端側から除去部４０が延設され、除去部４０がノズルガイド部２２側となるように本体部２０の挿通穴２１ａを経て、内側に嵌められるとともに本体部２０の軸線方向に沿って摺動可能に形成され除去部４０を保持する保持ベース部３０と、を有し、除去片４１、４２が、ガイド面２２ｅにノズルＮ及びチップＫが挿入されるときに、溶接トーチＺのノズルＮ及びチップＫと干渉しない位置に退避した退避位置と、ノズルＮの内周面Ｎ１とチップＫの外周面Ｋ１との間の隙間部分への進入が完了した進入完了位置との間で、往復移動可能とすることが望ましい。 Further, the main body 20 is formed in a cylindrical shape and the nozzle guide portion 22 is disposed on one end side, and the removal portion 40 is extended from the one end side so that the removal portion 40 is on the nozzle guide portion 22 side. 20 through the insertion hole 21a, and a holding base portion 30 that is formed to be slidable along the axial direction of the main body portion 20 and holds the removal portion 40. When the nozzle N and the tip K are inserted into the guide surface 22e, the retracted position retracted to a position that does not interfere with the nozzle N and the tip K of the welding torch Z, and the inner peripheral surface N1 of the nozzle N and the outer peripheral surface of the tip K It is desirable to be able to reciprocate between the entry completion position where entry into the gap with K1 has been completed.
　このような構成では、ガイド面２２ｅにノズルＮ及びチップＫを挿入するときに、除去片４１、４２を退避させておくことによってノズルＮ及びチップＫをキズつけることを防止することが可能となるとともに、ガイド面２２ｅでノズルＮの外周面Ｎ２をガイドした状態で、除去片４１、４２をノズルＮの内周面Ｎ１とチップＫの外周面Ｋ１との間の隙間部分へ進入させることが可能となるので、除去片４１、４２によってノズルＮ及びチップＫをキズつけることを防止することができる。このことは、ノズルＮ及びチップＫにキズがあると、スパッタが付着しやすくなるので、スパッタ除去後の溶接作業において、ノズルＮ内のガスの乱流の発生を抑制してスパッタの付着を防止することに寄与する。 In such a configuration, it is possible to prevent the nozzles N and the chips K from being scratched by retracting the removal pieces 41 and 42 when the nozzles N and the chips K are inserted into the guide surface 22e. At the same time, with the guide surface 22e guiding the outer peripheral surface N2 of the nozzle N, the removal pieces 41 and 42 can enter the gap portion between the inner peripheral surface N1 of the nozzle N and the outer peripheral surface K1 of the tip K. Therefore, the removal pieces 41 and 42 can prevent the nozzle N and the tip K from being scratched. This means that if the nozzle N and the tip K are scratched, spatter easily adheres to it, so in the welding operation after spatter removal, the occurrence of gas turbulence in the nozzle N is suppressed to prevent spatter adhesion. Contributes to
　また、保持ベース部３０を本体部２０に対して中心線Ｃを軸として回転することを防止する回転防止手段８０を有している。 Further, it has a rotation preventing means 80 for preventing the holding base portion 30 from rotating with respect to the main body portion 20 about the center line C.
　スライド部２５と本体部２０を一体で回転させることになるので、ノズルＮに対して除去片４１、４２を回転させながら引き離す方向に引っ張る作業を容易にすることができる。 Since the slide part 25 and the main body part 20 are rotated integrally, the work of pulling away the removal pieces 41 and 42 while rotating the removal pieces 41 and 42 with respect to the nozzle N can be facilitated.
　また、除去部４０を、複数の除去片４１、４２と、各除去片４１、４２を先端側で連結する連結部４３と、をそなえる構成とし、連結部４３には、チップＫをガイド可能なガイド孔４３ａを形成している。 Further, the removal portion 40 is configured to include a plurality of removal pieces 41 and 42 and a connection portion 43 that connects the removal pieces 41 and 42 on the distal end side, and the chip K can be guided to the connection portion 43. A guide hole 43a is formed.
　これによれば、各除去片４１、４２の自由端側を連結部４３で連結することで、強度を向上させるとともに、ガイド孔４３ａによりチップＫをガイドすることで、ガイド面２２ｅにノズルＮ及びチップＫを挿入するとき、除去片４１、４２をノズルＮの内周面Ｎ１とチップＫの外周面Ｋ１との間の隙間部分へ進入させるときに、芯合わせをしやすくすることができる。 According to this, by connecting the free end side of each removal piece 41 and 42 with the connection part 43, while improving intensity | strength, the chip | tip N is guided to the guide surface 22e by guiding the chip | tip K by the guide hole 43a. When the tip K is inserted, the removal pieces 41 and 42 can be easily centered when entering the gap portion between the inner peripheral surface N1 of the nozzle N and the outer peripheral surface K1 of the tip K.

　突出部２２ｇの挿通孔２２ｉの内周面が、除去部６０の各除去片６１、６２を外側から拘束する円環状の押え部２２ｊとして形成されている。 The inner peripheral surface of the insertion hole 22i of the protruding portion 22g is formed as an annular pressing portion 22j that restrains the removal pieces 61 and 62 of the removal portion 60 from the outside.
　また、スパッタ除去具１０Ａは、各拡開部６１ｃ、６２ｃを、退避位置において内側に互いに引き寄せられた縮径状態と、ノズルＮの内周面Ｎ１側に向かって拡径する拡径状態と、に保持可能とする保持手段７０を有している。 Further, the sputter removing tool 10A has a diameter-reduced state in which each of the expanded portions 61c and 62c is drawn toward each other in the retracted position, and a diameter-expanded state in which the diameter is increased toward the inner peripheral surface N1 side of the nozzle N. It has the holding means 70 which can hold | maintain.
　保持手段７０は、押え部２２ｊと、各拡開部６１ｃ、６２ｃを含む各除去片６１、６２の外周面と、で構成されている。 The holding means 70 is configured by a pressing portion 22j and outer peripheral surfaces of the removal pieces 61 and 62 including the expansion portions 61c and 62c.
　スパッタ除去具１０Ａの動作について説明する。以下の説明では、スパッタ除去具１０と共通する動作については、全部又は一部の説明を省略する。 The operation of the spatter removal tool 10A will be described. In the following description, all or a part of the operations common to the sputter remover 10 are omitted.
　図１０の退避位置における各拡開部６１ｃ、６２ｃの状態を縮径状態とし図１１の進入完了位置における各拡開部６１ｃ、６２ｃの状態を拡径状態とする。 The state of the expanded portions 61c and 62c at the retracted position in FIG. 10 is the reduced diameter state, and the state of the expanded portions 61c and 62c at the entry completion position in FIG.
　スライド部４５を、位置決め溝３０ｉが視認できる位置まで本体部２０から引き出し、退避位置に移動させる。 The slide part 45 is pulled out from the main body part 20 to a position where the positioning groove 30i can be visually recognized, and moved to the retracted position.
　図の退避位置において、押え部２２ｊは、各拡開部６１ｃ、６２ｃの端縁部６１ｄ、６２ｄと当接して各除去片６１、６２を外側から拘束することにより、各除去片６１、６２を外側に付勢した状態にするとともに、拡開部６１ｃ、６２ｃを縮径状態に保持している。このとき、各除去片６１、６２は位置決め面２２ｈより前側に突出しない位置にある。 In the retracted position shown in the drawing, the holding portion 22j abuts against the edge portions 61d and 62d of the expanded portions 61c and 62c to restrain the removed pieces 61 and 62 from the outside, thereby holding the removed pieces 61 and 62 from the outside. While expanding outwardly, the expanded portions 61c and 62c are held in a reduced diameter state. At this time, each removal piece 61 and 62 is in a position that does not protrude forward from the positioning surface 22h.
　ノズルガイド部２２のガイド面２２ｅに溶接トーチＺのノズルＮ及びチップＫを、ノズルＮの先端面Ｎ３が位置決め面２２ｈに突き当たるまで挿入する。各拡開部６１ｃ、６２ｃは、徐々に広がるように配置されているので、退避位置から進入完了位置まで、徐々に拡径していくことになる。 The nozzle N and the tip K of the welding torch Z are inserted into the guide surface 22e of the nozzle guide portion 22 until the tip surface N3 of the nozzle N hits the positioning surface 22h. Since each expansion part 61c, 62c is arranged so as to gradually expand, the diameter gradually increases from the retracted position to the entry completion position.
　図１１、１６の進入完了位置において、押え部２２ｊは、各除去片６１、６２の前後方向における各拡開部６１ｃ、６２ｃの端縁部６１ｄ、６２ｄと当接して各除去片６１、６２を外側から拘束することにより、各拡開部６１ｃ、６２ｃを拡径状態に保持している。 11 and 16, the holding portion 22j abuts against the edge portions 61d and 62d of the widened portions 61c and 62c in the front-rear direction of the removal pieces 61 and 62 so that the removal pieces 61 and 62 are brought into contact with each other. By constraining from the outside, each of the expanded portions 61c and 62c is held in an expanded state.
　このとき、各除去片６１、６２は、外側に付勢されて短手方向の端縁部６１ｄ、６２ｄがノズルＮの内周面Ｎ１に接触した状態になる。 At this time, the removal pieces 61 and 62 are urged outward, and the edge portions 61d and 62d in the short-side direction are in contact with the inner peripheral surface N1 of the nozzle N.
　スパッタ除去具１０Ａを、ノズルＮの中心線Ｃ（ノズルＮの軸線）に対して回転させながら引き抜く、このとき図１７（ａ）、（ｂ）に示すように、ノズルＮが外れてしまわないように右回りに回すのが望ましい。 The sputter remover 10A is pulled out while being rotated with respect to the center line C of the nozzle N (the axis of the nozzle N). At this time, as shown in FIGS. 17A and 17B, the nozzle N will not come off. It is desirable to turn it clockwise.
　各除去片６１、６２は、外側に付勢されて短手方向の端縁部６１ｄ、６２ｄがノズルＮの内周面Ｎ１に接触した状態にあるので、ノズルＮの外周面Ｎ２とガイド面２２ｅとの間の隙間によるガタつきがあっても、各除去片６１、６２の回転方向前側の短手方向の端縁部６１ｄ、６２ｄがノズルＮの内周面Ｎ１に接触可能となり、ノズルＮの内周面Ｎ１に付着したスパッタの除去を容易する。 Since each of the removal pieces 61 and 62 is biased outward and the edge portions 61d and 62d in the short direction are in contact with the inner peripheral surface N1 of the nozzle N, the outer peripheral surface N2 of the nozzle N and the guide surface 22e. Even if there is a backlash due to a gap between the nozzles N, the edge portions 61d, 62d in the short direction on the front side in the rotation direction of the removal pieces 61, 62 can come into contact with the inner peripheral surface N1 of the nozzle N. It is easy to remove the spatter adhering to the inner peripheral surface N1.
　スパッタ除去具１０Ａは、複数の除去片６１、６２で構成され、各除去片６１、６２は、弾性変形可能な部材でノズルＮの内周面Ｎ１を圧接可能に形成され、ノズルガイド部２２は、各除去片６１、６２を外側から拘束する円環状の押え部２２ｊを有している。 The sputter remover 10A is composed of a plurality of removal pieces 61 and 62, and each removal piece 61 and 62 is an elastically deformable member so that the inner peripheral surface N1 of the nozzle N can be press-contacted. Each of the removal pieces 61 and 62 has an annular holding portion 22j that restrains the removal pieces 61 and 62 from the outside.
　これによれば、押え部２２ｊにより、ガイド面２２ｅにノズルＮ及びチップＫを挿入するときに、退避位置では各除去片６１、６２を縮径状態とし、除去片６１、６２によってノズルＮ及びチップＫをキズつけることを防止し、進入完了位置に至るまで徐々に拡径させ、ノズルＮに対して各除去片６１、６２を回転させながら引き離す方向に引っ張ることで、容易にスパッタを剥離、除去することができる。また、スパッタ除去後の溶接作業において、スパッタの付着を防止したりすることもできる。 According to this, when the nozzle N and the tip K are inserted into the guide surface 22e by the holding portion 22j, the removal pieces 61 and 62 are reduced in diameter at the retracted position, and the nozzles N and the tips are removed by the removal pieces 61 and 62. Prevents scratching of K, gradually increases the diameter until reaching the entry completion position, and pulls away in a direction that separates the removal pieces 61 and 62 with respect to the nozzle N. can do. Moreover, adhesion of spatter can be prevented in the welding operation after spatter removal.
　特に、小径のノズルを使用するときで、複数の除去片を先端側どうして連結することが困難な場合に好適である。 Particularly, it is suitable when a small diameter nozzle is used and it is difficult to connect a plurality of removal pieces on the tip side.
　本発明のスパッタ除去具は上記構成に限定されるものではない。即ち、本発明の要旨を逸脱しない限り各種の設計変更等が可能である。 The sputter removal tool of the present invention is not limited to the above configuration. That is, various design changes can be made without departing from the gist of the present invention.
　例えば、除去部４０は、一対の除去片４１、４２で構成しているが、少なくとも一つの除去片で構成することもできるし、三つ以上の除去片で構成することもできる。 For example, although the removal part 40 is comprised with a pair of removal pieces 41 and 42, it can also be comprised with at least 1 removal piece, and can also be comprised with three or more removal pieces.
　また、除去部６０も、一対の除去片６１、６２で構成しているが、少なくとも一つの除去片で構成することもできるし、三つ以上の除去片で構成することもできる。 Moreover, although the removal part 60 is also comprised by a pair of removal pieces 61 and 62, it can also be comprised by at least 1 removal piece, and can also be comprised by three or more removal pieces.
　また、除去片６１、６２は、基部６１ｂ、６２ｂの前端から屈曲して外側に向かって拡開するように延設された拡開部６１ｃ、６２ｃを有する構成としているが、ノズルＮの内周面Ｎ１に接触してスパッタを除去できるのであれば、湾曲させることも可能である。 Further, the removal pieces 61 and 62 are configured to have expanded portions 61c and 62c that are bent from the front ends of the base portions 61b and 62b and extend outwardly. If the spatter can be removed by contact with the surface N1, it can be curved.
